If there's anything I hope to be, it's a student. StackOverflow appeals to me in the same way Slashdot once did: it's a constant stream of new terminology I can almost, but not quite, understand. As I acquire mastery in one area, a new item of interest begins inspiring questions and further opportunities to learn.

The majority of questions that I answer, I look up the answers and learn the subject with the asker. This may make my information inexpert on occasion, but it means I always check my work for correctness and often provide references that I used to research.

comment How do I tell real CPU load in a xen environment?
Yes, percent of CPU per core total. Like CPU core 1: 95%, 2: 90% 3: 86% and so on.

comment How do I tell real CPU load in a xen environment?
That gives per-VCPU total seconds. But no CPU %, which is what I'm after.

comment How do I tell real CPU load in a xen environment?
I don't see any way to view the utilization of individual CPU cores in xentop, only the total CPU % used by each virtual machine. Is there any way to get a per-core total?

Shot in the dark, but check /var/log/dpkg.log on the new system. Maybe apt had to update a whole bunch of packages, and the downloading/installing was affecting response time.

@Mark Well, it doesn't look like you're facing heavy swapping, which was my first guess.

What does free -m on the virtual system report?

comment Incredibly high latency for Ubuntu guest on Hyper-V
Have you verified that pings to the physical machine are not being lost as well, to ensure networking issues aren't present, or tried pinging directly from the host machine to one of the virtual machines?
